ports and 1.5

[Robert Huff]

	I currently have jdk-1.4.2p8_3 installed; I'd like to  upgrade
to 1.5.
	Before I build the new version then find out it doesn't work
with N>0 ports, is there a way to determine which ports don't work
for 1.5?  A maintained list, a script which checks Makefiles?
Anything?  Bueller?
